How hard is it for an adult to take up gymnastics?

I’m 27. I work out all the time, but I hate lifting weights. I think that gymnastics would be great exercise, and more fun. My question is this: How difficult will it be for me to start up? I have terrible balance and terrible coordination, but I believe it is all related to the fact that I have a weak core. What better way to build core strength than gymnastics? How hard will it be to find someone who will teach me? I am pretty flexible. I bend in ways normal people don’t. However, I am not gymnast flexible, I am double jointed flexible. Oh and I am a male.
